Objective:To investigate the separation of the enantiomers of four drugs-naproxen,ketoprofen,ofloxacin and atropine by capillary electrophoresis (CE)using highly sulfated cyclodextrins(HS-CDs) as chiral additives.Methods:On neutral fused silica capillary column,using triethylammonium phosphate solution(pH 2 5)as background electrolyte,and HS-α-CD,HS-β-CD,HS-γ-CD as chiral additives,capillary zone electrophoresis with the reversed-polarity mode was applied to examine the effect of the HS-CD type on the enantioseparation of the four drugs.Results:The optimal chiral selectors for ketoprofen,ofloxacin and atropine are HS-β-CD,and HS-γ-CD for naproxen.Base-line separation of the enantiomers of the four drugs were all obtained under their respective optimal CE conditions.Conclusion:HS-CDs are potential powerful chiral selectors in CE,which are worth developing further.
